Association between floral traits and rewards in Erysimum mediohispanicum (Brassicaceae).
BACKGROUND AND AIMS Floral rewards may be associated with certain morphological floral traits and thus act as underlying factors promoting selection on these traits. This study investigates whether some traits that are under pollinator-mediated selection (flower number, stalk height, corolla diameter, corolla tube length and corolla tube width) in the Mediterranean herb E. mediohispanicum (Bras...
متن کاملUsing complementary techniques to distinguish cryptic species: a new Erysimum (Brassicaceae) species from North Africa.
PREMISE OF THE STUDY Cryptic species are superficially morphologically indistinguishable and therefore erroneously classified under one single name. The identification and delimitation of these species is usually a difficult task. The main aim of this study is to provide an inclusive methodology that combines standard and new tools to allow accurate identification of cryptic species. We used Er...
متن کاملGeometric morphometrics of corolla shape: dissecting components of symmetric and asymmetric variation in Erysimum mediohispanicum (Brassicaceae).
Symmetry is an important feature of floral structure, and floral symmetries are diverse and often complex. We use a new morphometric approach for analysing shapes with complex types of symmetry, which partitions shape variation into a component of symmetric variation and different components of asymmetry. This approach, based on the mathematical theory of symmetry groups, can be used for landma...
متن کاملPopulation differentiation and plasticity in vegetative ontogeny: effects on life-history expression in Erysimum capitatum (Brassicaceae).
PREMISE OF THE STUDY Distinguishing the contributions of phenotypic plasticity vs. population differentiation to variation in the life history of plants throughout their range is important for predicting their performance after dispersal or their responses to environmental change. In Erysimum capitatum, plants in alpine environments are iteroparous perennials, but those below tree line are seme...
متن کاملCharacterization of microsatellite loci in Erysimum mediohispanicum (Brassicaceae) and cross-amplification in related species.
PREMISE OF THE STUDY We have developed and optimized microsatellite loci from a genomic library of Erysimum mediohispanicum. Microsatellites were also tested for cross-amplification in 31 other Erysimum species. METHODS AND RESULTS A total of 10 microsatellite loci were successfully amplified. They were polymorphic for 81 E. mediohispanicum individuals from two locations in Sierra Nevada (sou...
